It will thus be seen that the lever may be selectively and yieldinglyretained in position in operative or inoperative position as desired, sothat the operative connection of the vise screw with the vise jaws maybe established or broken as desired; 7

From the foregoing, the construction and operation of the invention,together with its many In order to selectively effect the locking orreleasing engagement of the half nut from the. vise screw, there isprovided a chamber 46 in the bottom portion of the base l2, this chamberintersecting the g-uideway 46. An operating lever is providedconsisting, as shown in Figure 7, of a shaft 48 which is journaled inthe base l2 between the chamber 46 and a forward'side of the base, thisshaft having rigidly but detachably secured to its outer end a handle52, and to its inner end an arm 50 which extends from the chamber 46into the guideway 40, the handle.

52 and the arm 50 extending in opposite directions from the axis of theshaft 48.

At one end, the arm 50 is provided with an elongated slot 54, while thefree end of the handle '52 is provided with a ball 56. The latterprovides a finger-grip portion by means of which the lever may bemanipulated. As shown best in Figures 3 and 5, the lower end of the halfnut 42 is provided with a slot 58 which receives the end of the lever50, a pivot pin 60 being disposed through the half nut 42, the slot 58,and the elongated slot 54 in the arm 50. It will thus be seen that uponoscillation of the lever, the half nut 42 will be verticallyreciprocated in its guideway 40 and thus moved selectively into and outof operative engagement with the screwthreaded portion 38 of the visescrew.

In order to selectively lock the lever into or out of operativepositions, a yieldable locking means is provided as shown in Figures 2and 6. For this purpose, that surface of the handle 52 which is adjacentto the base I2 is provided with a socket or recess 62, receiving acompres-- sion spring 64 which yieldingly urges a locking ball 66outwardly of the socket and against the adjacent surface of the base l2.The latter is provided with a pair of shallow recesses 68 and which areadapted to receive a portion of the surface of the ball 66 when thesocket 62 is in selected registry with either of the sockets 68 and 10.The sockets 68 and 10 are so placed that they will register with thesocket'SZ and the advantages will be readily apparent, and furtherexplanation is believed to be unnecessary. However, since numerousmodifications and changes will readily occur to those skilled in the artafter a consideration of the foregoing specification and accompanyingdrawings, it is not desired to limit the invention to the exactconstruction shown and described, but all suitable modifications andequivalents may be resorted to, falling within'the scope of the appendedclaim.

Having thus disclosed and described the invention, what is claimed asnew is as follows:

A bench vise comprising a base having a fixed jaw, a movable jaw, a visescrew carried by said movable jaw, a half nut slidably mounted in saidbase for radial movement toward and from said screw and engageableselectively with said vise screw, a lever journaled on said base, an armon said lever pivotally connected with said half nut for efiectingcontrolled movement of the latter, said split nut having an open-endedslot extending across one side of the half nut, said arm being receivedin the open end of said slot, a pivot extending across said slot andthrough the arm and split nut for connecting said arm to said split nut.
